AGILE Sensitivity and GRB Spectral Properties

Gamma Ray Bursts (GRBs) present different prompt and delayed emission properties which might suggest a possible taxonomy. Nonetheless, the existence of different classes could be the combined effect of different intrinsic and/or observational conditions. The latter, in particular, are related to the instrumental capabilities. For this reason, we studied the instrumental sensitivity of the AGILE satellite as a function of the spectral properties of GRBs. AGILE will be able to detect most of the bright-long bursts and its two detectors, with their independent trigger algorithms, compensate each other in detecting soft and high energy GRBs. Moreover, AGILE will possibly give a major contribution in the study of very energetic bursts with typical peak energies above ~ 1 MeV.
